Understanding LiDAR Technology

How LiDAR Works

LiDAR works by emitting laser beams and measuring the time it takes for those beams to return after hitting an object. This time-of-flight measurement is then used to calculate the distance to the object. By emitting and capturing thousands of these laser pulses per second, LiDAR creates a dense 3D point cloud representation of the environment. This point cloud data can then be processed to generate highly accurate depth maps and 3D models.

Unlike traditional cameras that only capture 2D images, LiDAR adds a crucial third dimension: depth. This makes it possible for Android phones to understand the spatial relationships between objects in their environment, enabling more realistic and immersive AR experiences.

LiDAR vs. Other Depth-Sensing Technologies

While LiDAR is not the only depth-sensing technology available, it offers several advantages over alternatives like stereoscopic cameras and structured light sensors. Stereoscopic cameras rely on two or more lenses to simulate human vision and estimate depth based on the disparity between the images captured by each lens. However, their accuracy can be limited by factors like lighting conditions and the texture of the objects being viewed.

Structured light sensors, on the other hand, project a known pattern of light onto the scene and analyze the distortions in the pattern to calculate depth. While they can be more accurate than stereoscopic cameras in certain conditions, they are typically limited to shorter ranges and can be affected by ambient light.

LiDAR offers the best combination of range, accuracy, and robustness, making it ideal for a wide range of applications. It works well in both indoor and outdoor environments and is less sensitive to lighting conditions than other depth-sensing technologies.
